Description

Technical Field

[0001] This invention relates to the field of precast T-beam production technology, and in particular to a rebar threading device for manufacturing the bottom web reinforcement cage of a T-beam. Background Technology

[0002] The main function of the precast T-beam production line is to achieve efficient, low-cost, and high-quality bridge component manufacturing through a standardized and modular production model. By using a moving platform to move between processes such as rebar binding, casting, and tensioning, the production cycle is significantly shortened, making it particularly suitable for situations where space is limited but large-scale production is required.

[0003] During the production of the bottom web reinforcement cage of T-beams, the bottom continuous bars of the bottom web reinforcement cage need to pass through the inside of multiple horseshoe bars and long stirrups. Since the length of large precast T-beams is more than 30 meters, and the length of the continuous bars is generally greater than the length of the precast T-beams, manual bar threading is time-consuming and laborious. Moreover, due to the long length of the continuous bars, the ends of the continuous bars are prone to bending downwards under the action of gravity. During the bar threading process, the continuous bars are prone to pass under the horseshoe bars and long stirrups, resulting in misalignment of the continuous bars.

[0004] Therefore, it is necessary to provide a new rebar threading device for manufacturing the bottom web reinforcement cage of T-beams to solve the above problems. Summary of the Invention

[0016] Compared with related technologies, the rebar threading device for manufacturing the bottom web reinforcement cage of T-beams provided by the present invention has the following beneficial effects:

[0017] This invention provides a rebar threading device for manufacturing the reinforcing steel skeleton of the bottom web of a T-beam. When the continuous reinforcing bar is threaded, the continuous reinforcing bar slides on the surfaces of the first roller and the second roller, which support and guide the continuous reinforcing bar. If the installation position of the continuous reinforcing bar located between the horseshoe-shaped reinforcing bar and the long stirrup is too close to the horseshoe-shaped reinforcing bar or the long stirrup, the continuous reinforcing bar is prone to colliding with the horseshoe-shaped reinforcing bar or the long stirrup during the threading process. Therefore, the first rollers that transport these four continuous reinforcing bars are all far away from the horseshoe-shaped reinforcing bar and the long stirrup, and the rollers push the continuous reinforcing bar upwards to avoid collision between the continuous reinforcing bar and the horseshoe-shaped reinforcing bar and the long stirrup.

[0018] When the end of the continuous rib moves between two adjacent rollers, under the action of gravity, this part of the continuous rib will droop downwards, causing the end of the continuous rib to be unable to fall onto the next roller. A guide plate is installed in front of each roller so that the drooping end of the continuous rib contacts the guide plate. The side wall of the guide plate has an arc-shaped cross section, which facilitates the end of the continuous rib to move upwards along the side wall of the guide plate. The surface of the guide plate is funnel-shaped, so that the continuous rib moving inside the guide plate gradually moves to the center of the surface of the guide plate, aligning the continuous rib with the roller, which facilitates the end of the continuous rib to move onto the next roller, and quickly performing the rib threading operation.

[0019] After the longitudinal reinforcing bar is threaded through, the pulling mechanism operates, driving the support shaft and the longitudinal reinforcing bar to move, aligning the longitudinal reinforcing bar located between the horseshoe-shaped reinforcing bar and the long stirrup with its installation position. The hydraulic rod located at the center of the trolley's bottom surface is opened, causing the roller and the longitudinal reinforcing bar to move linearly downwards, bringing the longitudinal reinforcing bar to its installation position against the surfaces of the horseshoe-shaped reinforcing bar and the long stirrup. The hydraulic rod at the center of the trolley's bottom surface continues to retract, driving the support shaft and roller to continue rotating downwards, causing the limiting rod to press against and squeeze the longitudinal reinforcing bar. As the roller continues to move downwards, on the longitudinal reinforcing bar corresponding to the first roller, the limiting rod rotates and squeezes the strong spring until the bottom end of the limiting rod touches the first limiting block. The first limiting block fixes the limiting rod, and the limiting rod with its top tilted upward hooks the continuous reinforcing bar, increasing the stability of the continuous reinforcing bar on the surface of the horseshoe reinforcing bar and the long stirrup. On the continuous reinforcing bar corresponding to the second roller, the second roller is installed on both the first support shaft and the second support shaft. The number of limiting rods on the surface of this continuous reinforcing bar is twice the number of limiting rods on the surface of other continuous reinforcing bars, and the limiting rods fix and compress the continuous reinforcing bar from different angles to prevent the continuous reinforcing bar from shifting, which facilitates the subsequent welding of the continuous reinforcing bar to the horseshoe reinforcing bar and the long stirrup.

Figure 12 for Figure 2The diagram shows the interior of the installation box. The rebar threading device for manufacturing the bottom web reinforcement cage of the T-beam includes a trolley 3 for moving the bottom web reinforcement cage around the workstation. Multiple clamping plates 32 are fixedly connected inside the trolley 3. The internal parts of the clamping plates 32 engage the reinforcing bars 33, and guide blocks 37 are installed on the surface of the clamping plates 32 to guide the reinforcing bars 33. The sidewalls of the guide blocks 37 are inclined. Multiple drive wheels 36 are installed at the bottom of the trolley 3, and drive motors 13 are installed on the sidewalls of the drive wheels 36 to drive them. The device is used for lapping the bottom web reinforcement cage of the T-beam. During the scaffolding process, after the horseshoe-shaped tendons 33 and the long stirrups 34 are welded, they are placed inside the clamping plate 32. The surface of the clamping plate 32 is provided with guide blocks 37 with inclined sidewalls, which facilitates the horseshoe-shaped tendons 33 to slide into the interior of the clamping plate 32, thereby fixing multiple horseshoe-shaped tendons 33 and long stirrups 34 inside the trolley 3. The drive motor 13 drives the drive wheel 36 to rotate, thereby pushing the trolley 1 to run in the factory assembly line, which facilitates further processing of the horseshoe-shaped tendons 33 and long stirrups 34.

[0035] The connection of the trolley 3 is connected by bolts to install connecting plates 35, and the side walls of the trolley 3 are symmetrically fixed to fixed plates 31; the length of the trolley 3 is generally about 4 meters, while the length of the precast T-beam is about 30 meters. During the assembly of the bottom web steel reinforcement skeleton, multiple trolleys 3 are spliced ​​together, and connecting plates 35 are installed by bolts at the connection of the trolleys 3, so that two trolleys 3 of the beam are connected together.

[0036] A feeding mechanism 2 is provided on one side of the trolley 3 to drive multiple continuous reinforcing bars 12 through the horseshoe-shaped reinforcing bars 33 and long stirrups 34; a chain conveyor belt 1 for conveying and fixing the continuous reinforcing bars 12 is installed at one end of the feeding mechanism 2; a drive motor 13 for driving the conveyor chain 15 to rotate is installed on the side wall of the chain conveyor belt 1; multiple teeth 14 for conveying the continuous reinforcing bars 12 are installed on the surface of the conveyor chain 15; a hydraulic rod 52 is installed on the surface of the chain conveyor belt 1; a positioning plate 11 is connected to the top of the hydraulic rod 52; multiple positioning grooves 16 with semi-circular cross sections are provided on the surface of the positioning plate 11; the continuous reinforcing bars 12 are slidably connected inside the positioning grooves 16; the feeding mechanism 2 includes a guide rail 21, and the chain conveyor belt 1... A guide rail 21 is installed between the trolley 3 and the slide block 26. A lead screw 27 for driving the slide block 26 to move back and forth linearly is rotatably connected inside the guide rail 21, and a drive motor 13 for driving the lead screw 27 to rotate is installed on the side wall of the guide rail 21. A mounting box 23 is fixedly connected to the side wall of the slide block 26. A hydraulic rod 52 is installed at the top of the mounting box 23, and a hinged fixing clamp 23 is rotatably connected to the bottom of the mounting box 23, which engages with the longitudinal rib 12. A slot 24 is provided at the top of the fixing clamp 23, and a pin fixed to the side wall of the drive block 25 passes through and slidably connects to the inside of the slot 24. The drive block 25 is connected to the hydraulic rod 52. When the slide block 25 is in motion... When threading the through-rib 12, according to the spacing between the positioning slots 16, the through-rib 12 is placed on the retaining teeth 14. The drive motor 13 is turned on, and the conveyor chain 15 and the retaining teeth 14 rotate, thereby conveying the through-rib 12 to the top of the positioning slot 16. The conveyor chain 15 is turned off, and the hydraulic rod 52 on the side wall of the chain conveyor belt 1 is turned on, driving the positioning plate 11 to move upward. Since the cross-section of the positioning slot 16 is semi-circular, it is convenient for the through-rib 12 to enter the interior of the positioning slot 16, so that multiple positioning plates 11 push the through-rib 12 upward, aligning the through-rib 12 with the fixing clamp 23. The drive motor 13 on the side wall of the guide rail 21 is turned on. The drive motor 13 drives the lead screw 27 to rotate, and through the principle of screw transmission, pushes the slider 26, the mounting box 22, and the fixing clamp 23 to move along the guide rail 21, so that the through-rib 12 enters between the two fixing clamps 23; at this time, the lead screw 27 is closed, and the hydraulic rod 52 inside the mounting box 22 is opened. The hydraulic rod 52 pushes the drive block 25 and the pin shaft to move upward. The pin shaft moves upward inside the slot 24, pushing the fixing clamp 23 to rotate, so that the fixing clamp 23 closes and clamps the through-rib 12; then the drive motor 13 is reversed, pushing the slider 26, the fixing clamp 23, and the through-rib 12 to move towards the trolley 1;When the fixing clamp 23 approaches the trolley 3, the hydraulic rod 52 moves to open the fixing clamp 23. Repeating this operation causes the fixing clamp 23 to move back and forth, pushing the longitudinal rib 12 into the interior of the trolley 3.

[0037] The trolley 3 is internally equipped with a rebar threading mechanism 6 to prevent the continuous reinforcing bar 12 from misaligning and colliding with the horseshoe-shaped reinforcing bar 33 or the long stirrup 34. The rebar threading mechanism 6 includes a first support shaft 61 and a second support shaft 64, which are slidably connected to the interior of the trolley 3. The side walls of the first support shaft 61 and the second support shaft 64 are rotatably connected to a first roller 62 for conveying the continuous reinforcing bar 12 located between the horseshoe-shaped reinforcing bar 33 and the long stirrup 34. A fixing sleeve 65 is symmetrically slidably connected at the center of the first support shaft 61 and the second support shaft 64. Hydraulic rod 52 is installed at the bottom of 5, and the fixed sleeve 65 is rotatably connected to the second roller 63 for conveying the continuous rib 12 located inside the long stirrup 34; the side walls of the fixed sleeve 65, the first support shaft 61 and the second support shaft 64 are equipped with a connecting frame 66 for fixing the guide plate 67, and the guide plate 67, with an arc-shaped side wall cross section and a funnel-shaped surface, is fixed to one side of the first roller 62 and the second roller 63; the side wall of the guide plate 67 is fixedly connected to a fixing block 612, and the inside of the fixing block 612 is rotatably connected to a limiting rod 69 with a hook-shaped top end, and the limiting rod 69 is connected to... A strong spring 615 is installed between the fixing blocks 612; a first limiting block 613 and a second limiting block 614 with trapezoidal sidewall cross-section are installed on the sidewall of the fixing block 612 corresponding to the first roller 62, and a second limiting block 614 is installed on the sidewall of the fixing block 612 corresponding to the second roller 63. The inclined surfaces of the first limiting block 613 and the second limiting block 614 abut against the limiting rod 69; when the through-rib 12 penetrates the horseshoe rib 33 and the long stirrup 34, the through-rib 12 slides on the surfaces of the first roller 62 and the second roller 63. The first roller 62 and the second roller 63 support and guide the continuous reinforcing bar 12; the continuous reinforcing bar 12 located between the horseshoe reinforcing bar 33 and the long stirrup 34 is too close to the horseshoe reinforcing bar 33 or the long stirrup 34, and the continuous reinforcing bar 12 is prone to collide with the horseshoe reinforcing bar 33 or the long stirrup 34 during the reinforcing bar threading process. Therefore, the first roller 62 that conveys these four continuous reinforcing bars 12 are all far away from the horseshoe reinforcing bar 33 and the long stirrup 34, and the rollers push the continuous reinforcing bar 12 upward to avoid the continuous reinforcing bar 12 from colliding with the horseshoe reinforcing bar 33 and the long stirrup 34.When the end of the longitudinal rib 12 moves between two adjacent rollers, under the action of gravity, this part of the longitudinal rib 12 will droop downwards, causing the end of the longitudinal rib 12 to be unable to fall onto the next roller. A guide plate 67 is installed in front of each roller. The vertical distance between the lowest end of the guide plate 67 and the roller is not less than 10 cm, so that the drooping end of the longitudinal rib 12 contacts the guide plate 67. The side wall of the guide plate 67 is arc-shaped, which facilitates the end of the longitudinal rib 12 to move upwards along the side wall of the guide plate 67. The surface of the guide plate 67 is funnel-shaped, so that the longitudinal rib 12 moving inside the guide plate 67 gradually moves to the center of the surface of the guide plate 67, aligning the longitudinal rib 12 with the roller, which facilitates the end of the longitudinal rib 12 to move onto the next roller, and quickly perform the rib threading operation. During the threading process, the high-strength spring 615, which is always under compression, presses against the limiting rod 69. The limiting rod 69 bends downward and covers the surface of the guide plate 67, so that the limiting rod 69 covers the surface of the longitudinal rib 12, increasing the stability during the conveying of the longitudinal rib 12 and preventing the longitudinal rib 12 from detaching from the roller.

[0038] The surface of the trolley 3 is equipped with a pulling mechanism 5 for driving the first roller 62, the second roller 63, and the longitudinal rib 12 to move laterally. The pulling mechanism 5 includes guide rods 55, and multiple guide rods 55 are fixedly connected between the fixed plate 31 and the trolley 3. The guide rods 55 are slidably connected to the slide plate 55. The side wall of the slide plate 55 is symmetrically provided with first sliding grooves 54. The support frame 51 is slidably connected inside the first sliding groove 54. Multiple connecting rods 56 are fixedly connected to the bottom end of the support frame 51, and the bottom end of the connecting rods 56 is fixedly connected to the end of the first support shaft 61 or the second support shaft 64. The connecting rods 56 ensure that the support frame 51 is always above the support shaft, avoiding the support shaft from affecting the movement of the support rods 51. Multiple hydraulic rods 52 are installed on the side wall of the fixed plate 31, and the hydraulic rods 52 are connected to the side wall of the slide plate 55. After the longitudinal rib 12 is threaded through, the hydraulic rod 52 on the side wall of the fixing plate 31 is opened. The hydraulic rod 52 drives the sliding plate 53 to move along the guide rod 55. The sliding plate 53 drives the support frame 51 and the connecting rod 56 to move. The connecting rod 56 pushes the first support shaft 61 and the second support shaft 64 to slide inside the fixing sleeve 65, so as to prevent the position of the longitudinal rib 12 on the second roller 63 and its surface from changing. The first support shaft 61 and the second support shaft 64 drive the first roller 62 and the longitudinal rib 12 on its surface to move, so that the longitudinal rib 12 located between the horseshoe rib 33 and the long stirrup 34 is aligned with the installation position.Open the hydraulic rod 52 located at the center of the bottom surface of the trolley 1. The hydraulic rod 52 drives the "U"-shaped support rod 610, support shaft, rollers, and the longitudinal rib 12 to move downwards in a straight line, causing the longitudinal rib 12 to abut against the installation position of the horseshoe rib 33 and the long stirrup 34. At this time, the support rod 51 moves downwards inside the first slide groove 54, facilitating the adjustment of the support shaft position. After the longitudinal rib 12 abuts against the installation position, the hydraulic rod 52 located at the center of the bottom surface of the trolley 1 continues to retract. The hydraulic rod 52 drives the support shaft and rollers to continue rotating downwards, causing the limiting rod 69 to abut against and compress the longitudinal rib 12. As the rollers continue to move downwards, on the longitudinal rib 12 corresponding to the first roller 62, the limiting rod 69 rotates and compresses the strong spring 615 until the bottom end of the limiting rod 69 abuts against the first limiting block 613. The first limiting block 613 fixes the limiting rod 69, and the limiting rod 69, with its top tilted upwards, hooks onto the longitudinal rib 12, increasing the stability of the longitudinal rib 12 on the surfaces of the horseshoe rib 33 and the long stirrup 34. On the longitudinal rib 12 corresponding to the second roller 63, the second roller 63 is installed on both the first support shaft 61 and the second support shaft 64. The number of limiting rods 69 is twice the number of limiting rods 69 on the surface of the other longitudinal ribs 12, and the limiting rods 69 fix and compress the longitudinal ribs 12 from different angles to prevent the longitudinal ribs 12 from shifting and facilitate subsequent welding; after welding is completed, the hydraulic rod 52 on the side wall of the fixing plate 31 is opened. At this time, the hydraulic rod 52 extends and pushes the first support shaft 61 and the second support shaft 64 to move in opposite directions. At this time, the top of the limiting rod 69 corresponding to the first roller 62 is tilted upward, and the limiting rod 69 in contact with this longitudinal rib 12 moves away from this longitudinal rib 12, so that the longitudinal rib 12 can easily contact the longitudinal rib 12. The longitudinal reinforcement 12 is separated; then the hydraulic rod 52 located in the center of the bottom surface of the trolley 1 is opened, driving the support shaft and rollers to continue moving downwards. On the limiting rod 69 corresponding to the second roller 63, since there is no constraint from the first limiting block 613, the limiting rod 69 can continue to rotate and compress the strong spring 615. As the limiting rod 69 moves downwards, the longitudinal reinforcement 12 pushes the limiting rod 69 to rotate, causing the limiting rod 69 to separate from the longitudinal reinforcement 12 located inside the long stirrup 34; so that all the limiting rods 69 and rollers are located below the horseshoe reinforcement 33, thereby facilitating the removal of the web reinforcement cage inside the trolley 3.

[0039] The trolley 3 has a plurality of second sliding grooves 68 symmetrically arranged on its side wall. The first support shaft 61 and the second support shaft 64 are slidably connected inside the second sliding grooves 68. In order to facilitate the support shaft 61 to slide along the second sliding grooves 68 and change the height of the roller, the vertical distance between adjacent first support shafts 61 and the vertical distance between adjacent second support shafts 64 are between 80 cm and 100 cm. The first support shafts 61 and the second support shafts 64 are arranged alternately inside the trolley 3 in order to avoid the end of the long rib 12 from drooping too far downward and to facilitate the support of the long rib 12 by the first support shafts 61 and the second support shafts 64.

[0040] Multiple hydraulic rods 52 are installed at the center of the bottom surface of the trolley 3. Support rods 610 are installed at the top of each hydraulic rod 52, and the support rods 610 are fixedly connected to the fixed sleeve 65. In order to facilitate the hydraulic rods 52 to drive the rollers to move up and down, bearings 611 are fitted inside the fixed sleeve 65 and on the side walls of the first support shaft 61 and the second support shaft 64. The bearings 611 connect the first roller 62 and the second roller 63. In order to facilitate the through rib 12 to push the first roller 62 and the second roller 63 to rotate and reduce the resistance when the through rib 12 moves.

[0041] Multiple hydraulic rods 52 are symmetrically installed at the bottom edge of the trolley 3. The top of each hydraulic rod 52 is connected to a sliding sleeve 4. The interior of the sliding sleeve 4 is slidably connected to the first support shaft 61 and the second support shaft 64. Since the support shaft 64 is supported by the hydraulic rod 52 located in the center of the bottom surface of the trolley 3, and the support shaft needs to sway back and forth, the support shaft can be further supported by the sliding sleeve 4 and the hydraulic rods 52 at the bottom edge of the trolley 3, thereby increasing the stability of the support shaft.

[0042] The guide plate 67 has protective edges on both sides to prevent the through rib 12 from sliding off the surface of the guide plate 67; the axis of the guide plate 67 is in the same plane as the axis of the first roller 62 or the second roller 63, and the highest point of the guide plate 67 is aligned with the center of the top of the first roller 62 or the second roller 63, so that the through rib 12 can fall onto the surface of the roller along the guide plate 67.

[0043] The working principle of the rebar threading device for manufacturing the bottom web reinforcement cage of T-beams provided by this invention is as follows: When the device is connected to an external power source and the continuous rebar 12 is threaded, the trolley 3 moves to one side of the guide rail 21. The continuous rebar 12 is placed on the clamping teeth 14, and the conveying chain 15 and the clamping teeth 14 rotate to convey the continuous rebar 12 directly above the positioning groove 16; the hydraulic rod 52 drives the positioning plate 11 to move upward, lifting the continuous rebar 12 and aligning it with the fixing clamp 32. The fixing clamp 32 closes and clamps the continuous rebar 12. As the fixing clamp 23 moves back and forth, it pushes the continuous rebar 12 continuously into the interior of the trolley 3. At this time, the continuous rebar 12 slides on the surfaces of the first roller 62 and the second roller 63. The second roller 63 supports and guides the continuous reinforcing bar 12. Because the continuous reinforcing bar 12, located between the horseshoe-shaped reinforcing bar 33 and the long stirrup 34, is installed too close to either the horseshoe-shaped reinforcing bar 33 or the long stirrup 34, it is prone to collision with the horseshoe-shaped reinforcing bar 33 or the long stirrup 34 during the threading process. Therefore, the first rollers 62 that transport these four continuous reinforcing bars 12 are all located away from the horseshoe-shaped reinforcing bar 33 and the long stirrup 34, and the rollers lift the continuous reinforcing bars 12 upwards to prevent collisions between the continuous reinforcing bars 12 and the horseshoe-shaped reinforcing bar 33 and the long stirrup 34 (as shown in the attached figure). Figure 4 and attached Figure 5(As shown); when the end of the continuous rib 12 moves between two adjacent rollers, under the action of gravity, this part of the continuous rib 12 will droop downwards, causing the end of the continuous rib 12 to be unable to fall onto the next roller. A guide plate 67 is installed in front of each roller. When the end of the continuous rib 12 droops, it contacts the guide plate 67. The side wall of the guide plate 67 has an arc-shaped cross section, which facilitates the end of the continuous rib 12 to move upwards along the side wall of the guide plate 67. The surface of the guide plate 67 is funnel-shaped, so that the continuous rib 12 moving inside the guide plate 67 gradually moves to the center of the surface of the guide plate 67, aligning the continuous rib 12 with the roller, which facilitates the end of the continuous rib 12 to move onto the next roller, and quickly perform the rib threading operation. After the longitudinal rib 12 is threaded through, the hydraulic rod 52 on the side wall of the fixing plate 31 is opened. The hydraulic rod 52 drives the sliding plate 53 to move along the guide rod 55. The sliding plate 53 drives the support frame 51 and the connecting rod 56 to move. The connecting rod 56 pushes the first support shaft 61 and the second support shaft 64 to slide inside the fixing sleeve 65, preventing the position of the longitudinal rib 12 on the second roller 63 and its surface from changing. The first support shaft 61 and the second support shaft 64 drive the first roller 62 and the longitudinal rib 12 on its surface to move, so that the longitudinal rib 12 located between the horseshoe rib 33 and the long stirrup 34 is aligned with the installation position. The hydraulic rod 52 located in the center of the bottom surface of the trolley 1 is opened. The hydraulic rod 52 drives the support rod 610, support shaft, roller and the longitudinal rib 12 to move straight downward, so that the longitudinal rib 12 abuts against the installation position of the horseshoe rib 33 and the long stirrup 34. When the longitudinal rib 12 abuts against the installation position, the hydraulic rod 52 located at the center of the bottom surface of the trolley 1 continues to retract. The hydraulic rod 52 drives the support shaft and roller to continue rotating downward, causing the limiting rod 69 to abut against and press against the longitudinal rib 12. As the roller continues to move downward, on the longitudinal rib 12 corresponding to the first roller 62, the limiting rod 69 rotates and presses against the strong spring 615 until the bottom end of the limiting rod 69 abuts against the first limiting block 613. The first limiting block 613 fixes the limiting rod 69, and the top end tilts upward. The limiting rod 69 hooks onto the longitudinal rib 12, increasing the stability of the longitudinal rib 12 on the surfaces of the horseshoe rib 33 and the long stirrup 34; on the longitudinal rib 12 corresponding to the second roller 63, the second roller 63 is installed on both the first support shaft 61 and the second support shaft 64, and the number of limiting rods 69 on the surface of this longitudinal rib 12 is twice the number of limiting rods 69 on the surfaces of other longitudinal ribs 12, and the limiting rods 69 fix and compress the longitudinal rib 12 from different angles to prevent the longitudinal rib 12 from shifting, facilitating subsequent welding (as shown in the attached figure). Figure 6(As shown). After welding is completed, open the hydraulic rod 52 on the side wall of the fixing plate 31. At this time, the hydraulic rod 52 extends, pushing the first support shaft 61 and the second support shaft 64 to move in opposite directions. At this time, the top of the limiting rod 69 corresponding to the first roller 62 is tilted upward (as shown in the attached figure). Figure 6 As shown), the limiting rod 69, which is in contact with the continuous reinforcing bar 12, moves away from the continuous reinforcing bar 12, making it easy to separate the continuous reinforcing bar 12 from the continuous reinforcing bar 12; then the hydraulic rod 52 located in the center of the bottom surface of the trolley 1 is opened, driving the support shaft and roller to continue moving downward. On the limiting rod 69 corresponding to the second roller 63, since there is no constraint from the first limiting block 613, the limiting rod 69 can continue to rotate and squeeze the strong spring 615. As the limiting rod 69 moves downward, the continuous reinforcing bar 12 pushes the limiting rod 69 to rotate, making the limiting rod 69 separate from the continuous reinforcing bar 12 located inside the long stirrup 34; so that all the limiting rods 69 and rollers are located below the horseshoe-shaped reinforcing bar 33, thereby facilitating the removal of the web reinforcement cage inside the trolley 3.
